Explanation:
Your teacher wants you to isolate x.
We first undo the "minus d" by adding d to both sides. Then we divide both sides by b to undo the multiplication. In short, we follow PEMDAS in reverse undoing everything to isolate the variable.
So,
e = bx-d
e+d = bx
bx = e+d
x = (e+d)/b
Answer:
x = [tex]\frac{e+d}{b}[/tex]
Step-by-step explanation:
Given
e = bx - d ( add d to both sides )
e + d = bx ( isolate x by dividing both sides by b )
[tex]\frac{e+d}{b}[/tex] = x
